BRIQUET-MACHINE.

Specification of Letters Patent.

Patented Sept. 20, 1910.

Application led September 28, 1908. .Serial No. 455,000.

To all whom it may concern.'

Be it known that we, JOSEPH W. Pn'rnns, of' Pittsburg, in the county of Allegheny and State of Pennsylvania, and DAVID Ivns BROWN, ofl the same place, citizens of the United States, have invented certain new and useful Improvements in Briquet-Machines, of' which the following is a specification. l

Our invention relates to machines for compressing comminnted material such as cnlm, lignite and other waste fuel products into briquets and has for its object the improvement of' machines of' this character looking to a more rapid, efficient and economical operation, and consists in providing a revolving cylindrical table with a series of' groups of' molds therein and providing mechanism by which the table is given a step by step motion so as to bring each group of molds successively into position to be filled with the material and have it slightly compressed therein, then moved to another position where the material is submitted to great pressure to form it into blocks or briquets and finally moved to a position where the briquets are removed from the molds.

Our invention will be described in detail hereinafter and illustrated in the aecompanying drawings in which- Figure l is a. side view in elevation of." our improved briquet machine, Fig. 2, a top plan view, Fig. 3, an end View, Fig. 4, a detail view of the filling device and mechanism for giving the initial compression to the briquet material, Fig. 5, a side view of' the mechanism to give the material its final compression, Fig. 6, a top plan View of the mechanism shown in Fig. 5, Fig. 7, a detail View of the mechanism for ejecting the briquets, Figs. S and f), detail views of' the mechanism for revolving the drum, and Fig. 10, a detail view of the mechanism for locking the drum.

In the drawings similaireference characters will indicate corresponding parts in all of the views.

1 indicates the base of our improved machine having the easing 2 mounted thereon. At one end the casing 2 :is formed with two upright portions 3 having a cylindrical table or drum 4 revolubly mounted therebetween on bearings 5 secured to the adjacent sides of said uprights 3, said table being provided with a series of groups of holes G therein arranged at equal intervals around it and forming molds for forming the briquets by the mechanism to be hereinafter described.

Secured to the top of upright portions 3 is a filler-box 7 having a hopper 8 delivering thereto through lwhich the'material is fed to the box 7, said box 7 and hopper 8 being inclosed by double thick walls spaced apart to form a chamber 9 to hold steam to heat the box and hopper. The delivery orifice 10 of filler-box 7 is just large enough to uncover a single group of' holes or molds G above described.

11 indicates a plunger block slidably mounted in box 7 having an upwardly extending llange '12 aroundits edge to engage the inner surface ot' the box. The lower surface of' block 11 is provided with threaded sockets 13 in alinement with the holes in each group 6 under orifice 10 said sockets being surrounded by annular exteriorly threaded bosses 14.

15 indicates the pressure plate having an upwardly extending flange 1G around its edge and a horizontal web 17 formed integral with flange 16 and spaced apart from pressure plate 15. llate 15 is provided with a plurality of holes '1 8 of substantially the same size as the holes in groups (i and in alinement therewith while the web 17 is provided with holes ,15) smaller in diameter than holes 18 but centrally alined therewith.

Q0 indicates plungers having heads 20a mounted in holes 1S and stems 21 extending through holes 1S) and formed with threaded ends 21 that fit in threaded sockets 13.

22 indicates sleeves secured to threaded bosses lfl having their lower ends reduced in diameter as shown at 22 to snugly iit stems 2l o'tI the plungers 20 and forming an exterior annular shoulder 22" on the sleeve.

23 indicates a coil spring mounted on each sleeve 22 and engaging shoulder 22h thereon and web 17.

It will be understood from this description that when block 11 is raised by the instrumentality hereinafter described that the plungers 20 will also be raised and when their heads Q0a engage web 17 the pressure plate 15 will be raised, this motion being continued until the delivery orifice of' hopper 8 is uncovered by flange 16. The product will then pour from hopper 8 into fillerbox 7 and from filler-box 7 into the molds 6 until the block 11 is forced downwardly,

when the springs 23 will hold the web 17 iny will be lightly compacted in advance thereof. Vhen the lower surface of the plate 15 engages shoulder 7 a in filler-box 7, the plate and flange 16 and web 17 are halted so that the flange 16 remains in position covering the orifice of hopper 8, but the continued descent of the block 11 forces the plungers 20 downwardly through the plate 15 and still further compacts the material in advance of said plungers in molds 6. The operation just described is then repeated, the drum 3 being rotated by the mechanism hereinafter described so that the next succeeding group of holes or molds 6 are brought into position under the filler-box 7.

24indicates a table secured to uprights 3 and positioned under filler-box 7 to cover the inner ends of molds 6 while being filled as above described and 25 a segmental plate secured to said uprights and extending from table 24 to the repress mechanism to be hereinafter described to hold the compressed materialin the molds after leaving the table and before reaching the repress mechanism referred to.

26 indicates a shaft journaled in bearings 27 mounted on base 1 and 23 a slotted arm secured to said shaft, said arm and shaft being actuated by a drive shaft 29 journaled as shown and having a crank arm 30 secured thereto with a roller or shoe 30a loosely secured thereon that engages the slot 28'd in the arm, it being understood that the rotation of shaft' 29 and crank arm 30 imparts a rocking motion to the arm and shaft 26.

31 indicates another shaft journaled on supports 32 secured to the top of uprights 3, and 33 an arm secured to shaft 31 and connected to arm 28 by means of pitman 34. 35 indicates other arms secured to shaft 31 at each end of filler-box 7 and 36 links connecting arms 35 and the end iianges of block 11.

It will be understood from this construction that when shaft 26 is rocked a rocking motion is imparted to shaft 31 through arms 28A and 33 and pitman 34, and to block 11 and its connections above described by means of arms 35 and links 36 to raise and lower the pressure plate 15 and plungers 20.

37y indicates ratchet teeth formed in the outer surface of drum 4 there being as many teeth 37 in the drum as there are groups 0f molds 6 formed therein, each of said teeth comprising a notch 37aL having the engaging end 37b formed at substantially a right angle to the base thereof, and radially of the drum, and its rear end curved backwardly from the notch as shown at 37C and merging into the inclined surface 37d that ends at the next succeeding notch 37.

38 indicates a bearing plate secured to one of the uprights 3 and having a guide slot 33a in its upper face to support a block 39 slidably mounted thereon.

40 indicates a hook or claw pivotally secured to block 39 and adapted to engage ratchet teeth 37, said hook or claw having its engaging end formed with an engaging' point 40a on its inner or forward side and a curved rear edge 40" that engages the curved portion 3.7c when the block 39 reaches the extremity of its forward stroke to stop the motion of the drum 4 and also to throw the claw out of engagement with notch 37a preparatory to a reverse movement to engage the next tooth.

41 indicates an arm securedy to shaft` 26 and 42 a link connecting arm 41 and claw or hook 40, said arm 41 being so positioned on the shaft 26 that when the block 11, abovedescribed, is in its lower-most position and the plungers 2O are compressing the materialin molds 6 the claw 40 is at the extremity of its backward stroke, and ready toengage a tooth 37, so that when the block 1l starts upwardly the claw is swung into engagement with the notch 37a and t-he drum is rotated the distance of the length of the tooth so as to bring the next group of molds under orifice 10.

43 indicates a pin slidably mounted in y hole 44 in upright 3 and normally propelled by spring 45 so as to engage the end of drum 4 or seat in one of the sockets 4a therein.

432L indicates a roller on the end of pin 43,

46 a disk having a cam projection 46a positioned so as to engage roller 43a and 47 a sprocket wheel secured to the disk 46, said disk and sprocket wheel being journaled-on a stud shaft 47 a secured to one of the uprights 3.

43 indicates a shaft journaled in uprights 3, 48a asprocketwheel on one end geared to sprocket wheel 47 by means of chain 49, and a sprocket wheel 47 b on its other end geared to sprocket wheel 50, keyed to shaft 29, by means of chain 50a.

After leaving the initial press as above described the drum 4 is rotated so that each set of molds 6 is held in position to be repressed by the mechanism to be described now. v

5l indicates the casing at the'rear of the machine having the guides 52 secured to its top with the blocks 53 slidably mounted therein and connected by shaft 54.

wir. i nmmjigniil L M 55 and 56 indicate arms journaled on shaft 54, the free ends of said arms being pivotally secured to plunger block 57 and cross head 58 respectively. Block 57 is mounted by means of rollers 59 on bearing 60 secured to casing 5l and has plunger-s 6l secured thereto in alinement with the outer side of a group of molds G when the drum 4 is at rest. Cross head 58 is mounted on rollers 69. that bears on supports G3 adjacent to the rear end oficasing 51 and are connected to plunger block G4 inside of the drum 4 by means of bars 65. Block (34 is mounted on rollers 66 that rest on supports G7 secured to uprights 3 and has secured thereto plungers 68 in alincment with the inner side of the group of molds 6 and opposite to plunger 61.

69 indicates a shaft journaled in casing 51 having an arm 70 secured thereto provided with a slot 70a and another arm 71 also secured thereto.

72 indicates a link pivotally secured to arm 71 and having its free end bifurcated and pivotally secured to shaft 54 on each side of arms 55 and 56.

78 indicates a drive shaft suitably journaled and having crank arm 74 extending therefrom with a shoe 74 that rides in slot 701.

It will be understood that during each complete rotation of shaft 73 the arm 70 is rocked so as to draw the shaft 54 downward pushing the plunger-s G1 and 68 toward each other, to compress the material in molds G into solid cakes or briquets, and then returned to their normal position, the compression being slow while the Withdrawal of the plungers is made more quickly. Shaft 73 isvactuated by means of gear wheel 75 keyed thereto and actuated by any suitable motor (not shown) to give the shaft a continuous rotation.

76 indicates a beveled gear wheel also keyed to shaft 73, 77 a beveled gear wheel keyed to shaft 29, and 7 8 a shaft journaled in boxes 7 9 and having beveled pinions 8O and 8l geared to beveled gear wheels 7 6 and 77 respectively so as to actuate said shaft 9.9.

rlhe briquets are removed from the molds 6 by means of a block 82 slidably mounted in guides 83 secured to uprights 3 and having plungers 84 secured thereto to engage the briquets and push them out of the molds. The guides 83 are on the opposite side of uprights 3 from the position of the repress mechanism, the block 82 being operated by a lever 85 secured to an axle 8G journaled in bearings 87 secured to uprights 3, the upper arm of said lever being connected to block 82 by means of link 88 while its lower arm is connected to block G4 by means of a link 89 mounted in bearings 90 secured to said block.

It will be understood that when block G4 is moved so as to compress the material in the molds (3 as above described the block 75 is moved toward the drum 4 so that the punches 84 enter the molds G and remove the briquets therefrom and they drop onto any suitable table or conveyer (not shown).
